* library/demos/cscroll.tcl: add MouseWheel bindings for aqua.
* macosx/tkMacOSXCarbonEvents.c (TkMacOSXInitCarbonEvents):
* macosx/tkMacOSXMouseEvent.c (TkMacOSXProcessMouseEvent,
GenerateMouseWheelEvent): add support for kEventMouseScroll events
(smooth mouse wheel scrolling from mighty mouse or scrolling trackpad)
by handling kEventMouseWheelMoved on application target as well as on
dispatcher, in order to pick up synthesized MouseWheel events from
HIObject handler (c.f. QA1453); add support for horizontal scrolling
events by generating MouseWheel XEvent with Shift modifier.
